I am interested in building a Savage 7mm WSM to shoot 180 gr Bergers. All I have currently is a 7 mm WSM large shank barrel...nothing else. I'm looking for suggestions from Savage 7mm WSM shooters who may have had to build their rifles. I've seen forum traffic from some who want to start with a 30-06 long action instead of starting with a 270 WSM or 300 WSM and just swapping barrels? I definately want a DBM. The reason I think someone may recommend the 30-06 may be better is because the long action may give more clearance for the long round and may provide less feeding problems from a DBM. I'd love to hear from folks who have built a 7mm WSM from a 30-06 and any problems they've encountered. Thanks.
